Title: Screen distortion correcting circuit
Inventor: KOJIMA MITSUGI
IPC: H04N3/23
Filed: 1994-03-16
Abstract: PURPOSE:To easily perform a screen distortion correction for the horizontal parallelogram distortion of a screen and to unnecessitate an individual distortion correcting circuit by superposing a saw-tooth distortion correcting signal proportional to vertical deflection current to a horizontal phase adjusting circuit. CONSTITUTION:A saw-tooth wave voltage proportional to vertical deflection current is taken out from a vertical output circuit 9 and inputted to a screen distortion correcting means 10 so as to improve the horizontal parallelogram distortion. The screen distortion correcting means 10 converts the saw-tooth wave voltage into a screen distortion correcting signal corresponding to the horizontal parallelogram distortion. Then, horizontal phase shift amounts are changed in a saw-toothed shape by superposing the output of the correcting signal to a horizontal phase correcting voltage VS being the output of a frequency-voltage conversion circuit 7 and supplying the superposed output to a constant current circuit 8. That is, since the saw-tooth distortion correcting signal is generated by providing a difference between a reference signal obtained by converting the saw-tooth voltage detected by the vertical deflection current and a comparison signal, the position of horizontal picture is changed in the saw-tooth shape in vertical periods by superposing the output of the horizontal phase adjusting signal.

IPC: H03F1/52
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier protective circuit that prevents the heat destruction of a transistor for amplification which accompanies a rapid increase of power consumption when the transistor for amplification is continuously used for many time slots. SOLUTION: This circuit is provided with a transistor 1 for power amplification which is driven in time division and a base bias feeder circuit (configuration part surrounded by a dotted line) for the transistor 1. Here, the base bias feeder circuit has a transistor 3 for control in which a resistance voltage divider 4 is connected to a base and the base of the transistor 1 is connected to an emitter, causes a stationary current to flow into the transistor 3 and feeds normal base bias voltage to the transistor 1 when mean power consumption of the transistor 1 is stationary value, causes a saturation current to flow into the transistor 3 within a short time, feeds reduced base bias voltage to the transistor 1 and protects the transistor from heat destruction when the mean power consumption of the transistor 1 becomes an overpower state.

Title: Document priority giving method and device and storage medium storing document priority giving program
Inventor: HASEGAWA TAKAAKI
IPC: H04L12/54
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To easily decide an electronic document that should be fetched and read with preference by extracting the feature corresponding to an individual user of the received electronic document and also the urgency of the document and giving the priority corresponding to the user in response to the extracted feature and urgency. SOLUTION: A document receiving part 10 receives an electronic document that arrived at a terminal and decides whether a time limit is described on the document. If the time limit is described on the electronic document, a time limit extraction part 30 extracts the time limit and sends it to an urgency calculation part 40 which calculates the urgency (0 to 1) by a prescribed calculation method. A priority calculation part 70 calculates the weighted mean based on the urgency calculated at a part 40 and also on the degree of selection, i.e., the feature corresponding to an individual user that is calculated at a selection degree calculation part 60. Then the part 70 calculates the priority of the received electronic document and gives it to the user. Thus, it's possible to easily decide an electronic document that should be fetched and read.

Title: Substrate preparing apparatus
Inventor: YAMASHITA TETSURO
IPC: H01L21/027
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a substrate preparing apparatus capable of shortening a time required for the reaction of a film formed on a substrate on a treatment agent. SOLUTION: Methoxytriacetoxysilane(MTAS) is delivered from a treatment agent supply nozzle 22. A reaction accelerating liquid (a mixture liquid of IPA, water, and a base (TMAH)) is delivered from an acceleration agent supply nozzle 32. Both the agents are simultaneously delivered to a substrate W forming a SOG(spin-on-glass) film 1, so that in a state in which the MTAS and reaction acceleration liquid are mixed with each other, they are supplied to the SOG film 1. If the MTAS as ester is mixed with the reaction acceleration agent, the MTAS is hydrolyzed with the TMAH and water, and MTHS is formed. The hydrophile MTHS interacts quickly with the hydrophilic SOG film 1. That is, the time for requiring a reaction of the MTAS on the SOG film 1 with the reaction acceleration agent can be shortened.

Abstract: PURPOSE:To increase the etching rate of an Si material without increasing the consumption of electric power from a power source, by coating the vacuum vessel, the substrate electrode and the opposite electrode of the titled reactive ion etching device with polytetrafluoroethylene. CONSTITUTION:Coating is applied onto the inner surface of a vacuum vessel 8, and a substrate electrode 11 and an opposite electrode 12 inside the vessel 8 as shown in the drawing, using polytetrafluoroethylene. A substrate 14 to be etched is mounted on the electrode 11, the vessel 8 is evacuated through an exhaust opening 9, treating gas comprising a fluoric compound is sent through piping 10 into the vessel 10, and ion etching is performed using a high-frequency power source 13. Hereon, when the discharge of the treating gas is started, substance contributive to etching is formed from said polytetrafluoroethylene in addition to substance such as the ions or radicals of fluorine or fluoric compounds contributive to etching from the treating gas. Hence, the etching rate of an SiO2 film can be increased without reducing the selection ratio of an etching rate to a resist.

Filed: 1983-03-18
Abstract: PURPOSE:To improve remarkably the measuring accuracy by utilizing that one side wave of a Harris system AM stereo signal wave is cancelled when L and R signals different in phase by 90 deg. with the same level and frequency are applied. CONSTITUTION:When the L and R signals different in phase by 90 deg. with the same frequency and level are applied, the relation of (L+R) and (L-R) signals is also the relation of the signals different in phase by 90 deg. with the same frequency and level and one side wave is cancelled by the principle of the synthesizing system SSB. The ratio of levels of upper and lower side waves corresponds to the degree of separation. A signal 54:cospt is applied to an L signal input terminal 56 of an AM stereo signal generator 58 from an MAIN output terminal 52 of a low frequency oscillator 51, a signal 55:cos(pt+pi/2) is applied to an R signal input terminal 57 from a QUAD output terminal 53 and both signal levels are matched identical. An AM stereo signal 60 of an AM stereo signal generator 58 is observed by a spectrum analyzer 61 and the level ratio of the upper and lower side waves is measured to obtain the degree of separation.

Title: Picture information encoder
Inventor: UNO YOSHIHIRO
IPC: H04N1/415
Filed: 1986-03-04
Abstract: PURPOSE:To realize an excellent reproduced picture and a high code compression ratio by dividing picture information into blocks and recognizing a pattern at every block at the time of encoding picture information. CONSTITUTION:Plural stored picture elements and sampled and quantized picture elements to be stored are added to comprise one block. With said block as the unit for recognizing a pattern the 1st encoder 105 recognizes a pattern. When a recognition ratio PR exceeds a fixed value PN, a pattern code corresponding to the recognized pattern is taken for a code of the picture elements comprising one block. If said PR is below the PN, the 2nd encoder 106 carrying out facsimile encoding attains a compression code for the picture elements comprising one block. A device 112 controlling the code transmission gives a control code to said codes and temporarily stores them, thereby achieving the high efficiency encoding of picture information.
